EJB Services

WSO2 WSAS has the ability to expose Enterprise Java Beans (EJB) as Web services. Once you have the EJB deployed in your application server, all you have to do is give the WSO2 WSAS the location of the archive containing the remote/home interfaces, enter the details for the interface, and give the JNDI bean names. The WSO2 WSAS will take care of exposing the EJB as a Web service. The WSO2 WSAS will communicate with the EJB using JNDI, which the WS client sees as just another Web service.

Deploying EJB Services

  1. In the navigator, under Manage/Service, click EJB Services. The EJB Services page appears.
  2. Select Use Existing or Add New, to use an existing application server or to configure a new application server respectively.

Adding a New Server

  1. If you selected Add New, select your server from the Server Type list. WSAS comes pre-configured with some of the settings for the following application servers: JBoss, Apache Geronimo, and BEA WebLogic. If you use an application server other than those available in the list,select Generic. Refer to your application server documentation/configuration for the values and the field descriptions.
  2. Enter values for the Provider URI and JNDI Context Class fields.
